BORDER-LIn-E-RULING PEN.

To all whom it may concern. v

Be it known that I, CARL WJBInSER, a citizen of the United. States, residlng at Dayton," in the" county of Montgomery ,and N State of Ohio, have invented a certainnew and useful Improvement in Border-Line Ruling Pens, of which the following is a specification.

This invention relates to a new and useful improvement in' border-line ruling pens.

The principal object of my' invention is to provide a simple and efficient ruling pen which will draw a wide border line in a neat and regular manner.

At present, where border lines are drawn with the pointed co-acting blades, it is diflicult to make a wide line without blotting the paper. This is largely due to the fact that the co-acting blades must be set at such a distance apart. for a wide line, that it is dillicult for them to retain all the ink contained between them, with the result that someof it adheres to the straight edge or other guiding member to be deposited thereby on the paper.

My invention obviates the above dilficulty by providing a cooperating guiding device for the co-acting blades, whereby their lower ends need not be pointed, but are out straight across and of a width to correspond to that of the border line to be drawn, whereupon they may be drawn over the paper to form a neat and regular line without danger of blotting it.

The preferred form of embodiment of my invention is illustrated in the accompanying drawings, of which Figure 1 is a top plan view of my improved border-line ruling pen.

' Fig. 2 is a side view thereof. And Fig. 3

is a front end view of said pen.

Throughout the specification and drawings, similar reference characters denote corresponding parts.

In a detailed description of the preferred form of embodiment of my invention, the numeral 1 designates a preferably cylindrical pen handle which fits into a knurled coupling sleeve 2. The latter in turn tightly receives the head portion 3 of the spring pen now to be described.

Referring to Figs. 1 and 2, the markin or drawing elements consist of a rigid bla e 4 and a spring blade 5 in superimposed relation, and whose opposing faces are flat and outer surfaces convex. These blades 4 and 5 are integral with, and extend outwardly from, the head 3, having ends that are prefera'bly cut straight across and of a width corresponding that of the border line to be drawn.

For the purpose of controlling the spacing of the blades to regulate the flow of ink therefrom, there is provided a set screw 6 which loosely passes through the spring blade 5 into a threaded hole in the rigid blade 4. The setscrew 6 has a knurled head 7 which may be turned to move the outer end of the spring blade 5 toward and away from the rigid one.

Fixedly secured by screws 8 8 or other means, between the rear ends of the blades 4 and 5 behind the set screw 6, is a guiding arm 9. The latter preferably consists of a relatively flat metallic piece which extends outwardly and downwardly to the plane of the tips of the pen blades l and 5, at a sufficient distance from them to prevent any ink which they contain from being transferred to the straight edge or other member in engagement with which the arm travels to guide the pen. Accordingly, after the blades are filled with ink to draw the border line desired, the blades themselves will not bear against the straight edge or other guiding member employed, but instead will be guided in their movement by the arm 9, which contains no ink and therefore can deposit none upon the drawing paper. Thus it is possible to hold the pen, when drawing, in a position wherein the convex portion of the bottom blade will face the paper, whereupon there will be produced a neat and regular line of a width corresponding to that of the straight bottom edges of the blades, with no danger of blots being formed upon the paper through contact of the ink with the guiding element used.

I do not wish to be limited to the details of construction and arrangement herein shown and described, and any changes or modifications may be made therein within the scope of the subjoined claims.

Having described my invention, I claim:

1. A border-line ruling pen comprising a pair of co-acting blades having tips whose width corresponds to that of the border line to be drawn, means for controlling the spacing of said blades, and a guiding arm extending downwardly from the base portions of said blades to a point at the side of and in approximate alinement with the bearing edge of their tips, to cooperate with the latz Specification of I ietterslPatent.
